The tool used for checking the external diameter of a round bar is called a caliper, specifically a digital or dial caliper. These calipers can accurately measure the diameter by using their jaws to grasp the round bar at its widest point. Alternatively, a micrometer can also be used for more precise measurements, particularly for smaller diameters. Both tools are essential for ensuring that the round bar meets specified dimensions in manufacturing and engineering applications.

The two types of measurements taken with a vernier caliper are internal measurements and external measurements. Internal measurements are used to measure the diameter or width of an object, while external measurements are for measuring the length or thickness. Additionally, a vernier caliper can also measure the depth of an object using its depth rod. This versatility makes it a valuable tool in various fields such as engineering and woodworking.
To show the diameter of an object, measure the distance across the object through its center using a ruler or caliper. Ensure that the measuring tool is aligned straight across the widest part of the object. For circular objects, you can also use a string to measure around the circumference and then calculate the diameter using the formula: diameter = circumference/π. Finally, visually indicate the diameter by marking the endpoints on the object or using a diagram.

A micrometer is a common instrument used to measure the external and internal diameter of a test tube. It is a precision tool that provides accurate measurements of small distances. Another option is a caliper, which can also be used for measuring diameters.
Here is a url that shows how to make the guillotine tool - the tool that holds the fuller: http://www.britishblades.com/forums/showthread.php?78415-Guillotine-tool-quot-how-to-quot To make the fuller, simply round the ends of the two dies or weld a piece of round stock (the diameter of the die thickness) on to the die faces to make the fullers. Other adaptations can be made, limited only by your imagination.

To accurately measure the diameter of a screw, use a caliper or a micrometer. Place the screw between the jaws of the measuring tool and tighten it gently. Read the measurement displayed on the tool to determine the diameter of the screw.

A SWOT analysis is an internal assessment tool used to evaluate a company's strengths and weaknesses, as well as opportunities and threats in its external environment.

In a turret lathe, internal and external tapers can be turned using a taper attachment or by setting the tool at an angle relative to the workpiece. For external tapers, the tool can be adjusted to cut at the desired taper angle while rotating the workpiece. Internal tapers can be achieved by using a boring tool set at the correct angle or by adjusting the tool post position. This allows for precise taper machining on both internal and external surfaces.
Depends on what you're checking. A piece of window glass works well for checking push rods for straightness. A machinists straight edge is good for checking heads and decks.
